Google has entered into an agreement to acquire the mobile phone and tablet maker Motorola Mobility for about $12.5 billion (£7.7 billion).
The company has offered about $40 per share in cash, a premium of 63 percent over the closing price of Motorola Mobility shares on Friday.
Motorola Mobility exclusively ships phones and its Xoom tablet with Google's Android operating system. The deal will mean that Google now has a hardware manufacturer to work with closely to develop Android, said Carolina Milanesi, research vice president at Gartner.
Google will also have control of Motorola's impressive patent portfolio, Milanesi said. Motorola Mobility said earlier this year that it owns about 24,500 patents.
But the deal may also create tension with other mobile phone manufacturers such as HTC and Samsung, which also ship Android devices, she said. Since creating Android, Google has rotated manufacturers with which to release new Android code, releasing the code to others about six months later.
Google may risk alienating those other manufacturers, but Milanesi said "all these vendors have invested so much in the platform, they won't quickly walk away from it".
Google may also want to speed up the development of its Android operating system on tablet computers, where it has been slower to catch on than on mobile phones, Milanesi said. The next release for Android, code-named "Ice Cream Sandwich," will be an operating system designed for tablets and mobile devices.
Google said the acquisition will "supercharge the Android ecosystem and enhance competition in mobile computing," according to a news release. Google said the deal will not affect how Android is developed, and the operating system will remain open, Google said.
The company will run Motorola Mobility, which has about 20,000 employees, as a separate business, Google said. The transaction is expected to close at the end of this year or early next year.
Motorola Mobility, which was spun off from its parent company in early January, is composed of two groups: Mobile Devices, which makes phones, and Home, which makes set-top boxes and other IPTV equipment.
